Searchlight system for vehicle post

A searchlight assembly comprising:

• a base portion,
• a post portion rotatably mounted to the base portion, the post portion having a hollow interior with a transverse conduit extending therethrough,
• a head portion pivotably mounted to the post portion opposite the base portion, the head portion having an optical device, and
• a pan/tilt mechanism comprising a plurality of components including two reversible motors, two belts, two rotatable lower gears, two rotatable bevel gears, and a stationary bevel gear, with the plurality of components forming two symmetrical drivetrains of the pan/tilt mechanism,
• wherein, in each drivetrain of the two symmetrical drivetrains, a respective reversible motor is drivingly connected to a respective belt, the belt is drivingly connected to a respective lower gear, the lower gear is drivingly connected to and positionally fixed relative to a respective rotatable bevel gear, and the rotatable bevel gear is drivingly connected to the stationary bevel gear,
• wherein the reversible motors are fixedly mounted to the head portion, and the lower gears are rotatably mounted relative to the head portion,
• wherein the stationary bevel gear is located in the hollow interior of the post portion and positionally fixed relative to the base portion, and the rotatable bevel gears engage the stationary bevel gear via the transverse conduit of the post portion,
• wherein for pan motion, the rotatable bevel gears are driven in the same rotational direction around the stationary bevel gear, such that the post portion and head portion rotate relative to the base portion, and
• wherein for tilt motion, the rotatable bevel gears are held motionless on the stationary bevel gear due to counteracting torques applied to the rotatable bevel gears, such that the head portion pivots relative to the post portion and the base portion.
